Iran CAO CPL Theory study plan

Map every line item of the Air Law syllabus to its source - the 1944 Chicago Convention and its key articles (1, 5, 6, 12, 30, 32), ICAO Annexes 1, 2, 6, 8, 11, 12, 14, 15 and 17, and the corresponding Iran CAO civil aviation regulations - and flag anything you cannot source for an instructor.

Distinguish CPL privileges, ratings, recency and renewal from PPL rules, and list the medical, currency and logbook conditions that keep a CPL valid in Iran.

Apply the rules of the air: VFR/IFR minima, cruising levels, right-of-way, aircraft lights and markings, and interception procedures, answering 30 recall questions closed-book.

Explain aircraft documentation and nationality/registration marks, and how the state of registry and state of the operator duties differ for a commercial pilot.

Explain how an ATC clearance, position reporting and the Tehran FIR structure fit the rules you have learned, using the Iran AIP as your reference.

Trace air and fuel from intake to exhaust in a horizontally opposed piston engine, and explain the role of the magnetos, carburettor or fuel injection, oil system and constant-speed propeller.

Draw and label the airframe structure, primary and secondary flight controls, trim and flap types with their operating limits for a typical CPL training aircraft.

Compare hydraulic, pneumatic, electrical, fuel and pressurization systems, and state what the pilot loses and which checklist action follows when a pump, alternator or bus fails.

Explain ice, rain and fire protection systems: where ice forms, what detects and removes it, and where fire detection and suppression are installed.

Decode METAR, SPECI and TAF completely, including CAVOK, RVR, trend groups and colour codes, and convert between QNH, QFE and pressure altitude.

Explain the hazards of weather typical of Iranian airspace: summer dust and haboobs in the southwest, Shamal winds, winter radiation fog around Tehran, and orographic cloud over the Alborz and Zagros.

Predict icing, thunderstorm life cycle, wind shear and microburst effects, and state the go/no-go decision a VFR or IFR commercial pilot makes in each case.

Interpret SIGMET, AIRMET, significant weather charts, wind and temperature aloft charts and satellite imagery, and relate them to a route decision.

Apply altimetry in practice: transition altitude and level, lowest usable flight level, and the temperature error of the altimeter in cold air.

Solve the wind triangle both ways: from TAS, heading and wind obtain track, groundspeed, drift and ETA, and from a required track obtain the heading to fly.

Convert between true, magnetic and compass headings using variation, deviation and isogonal/agonic lines, and show the conversion order on a flight log.

Describe the principle, indications, errors and failure flags of VOR, DME, NDB/ADF, ILS and GNSS/RNAV, and select the correct aid for each phase of an IFR flight in the Tehran FIR.

Apply chart work: chart scale, Mercator and Lambert conformal conic properties, great-circle versus rhumb-line tracks, and time-zone conversion for ETA reporting.

Derive the take-off and landing distance chain (TORA, TODA, ASDA, LDA) and apply it to flight manual charts, correcting for pressure altitude, temperature, mass, wind, runway slope and surface.

Compute climb gradients and obstacle clearance, and decide whether a departure procedure is legal for the planned mass and temperature.

Explain lift generation, induced and parasite drag and the L/D ratio, and use them to justify the speeds for maximum endurance and maximum range.

Analyse stall, load factor and turning performance, showing why stall speed rises with bank angle and mass, and explain static and dynamic stability about all three axes.

Explain how flaps, trim, CG position and propeller slipstream change control effectiveness and performance.

Build a complete fuel plan - taxi, trip, contingency, alternate, final reserve and extra fuel - and justify each figure against the regulation and the operator's policy.

Calculate mass and balance: convert between mass, weight and moment, use datum and arm, compute %MAC, and verify the CG stays inside the envelope at take-off, after fuel burn and at landing.

Complete an ICAO flight plan and a PLOG with fuel, ETA and alternate data for a 300 NM IFR route in the Tehran FIR.

Explain how CG position trades off against cruise performance, stability and stall speed, and complete a loading and trim sheet for a real training aircraft.

Apply normal, abnormal and emergency checklist philosophy: when to use a memory item, when to read the checklist, and how to divide tasks between pilot flying and pilot monitoring.

Describe engine failure and fire, rapid depressurization, ditching, evacuation and unlawful interference, together with the MAYDAY/PAN PAN calls and the content of each.

Explain pitot-static instruments, altimeter errors and the altimeter setting procedure across transition altitude and level, including cold-temperature corrections.

Describe gyroscopic and magnetic instruments, their power sources and failure indications, and the basics of EFIS, EICAS/ECAM and warning systems.

Explain hypoxia, hyperventilation, decompression sickness, spatial disorientation and the visual illusions of approach and landing, and the corrective action for each.

Assess fatigue, circadian rhythm, stress, alcohol and drugs, and vision and hearing limits against the flight-time and medical rules, and set personal minimums.

Practise standard radiotelephony for ground, tower, approach and en-route phases, including readback requirements, position reports and distress and urgency calls.

Sit two full-length timed mocks under exam conditions and convert the error log into a final 72-hour revision list ordered by frequency of error.
